5.6 Typical Power Block Device Characteristics

The typical power block system characteristic curves (Figure 1 through Figure 6) are based on measurements made on a PCB design with dimensions of 4 in (W) × 3.5 in (L) × 0.062 in (H) and 6 copper layers of 2-oz copper thickness. See Application and Implementation section for detailed explanation. TJ = 125°C, unless stated otherwise.
